The thrash down the motorway is probably a good idea.
After changing the oil a few times (with miles in between) I drove it to London (about 230 miles), which seemed to cure the problem.
Since then a new issue has arisen, but I'm working on that one...
thats what im hoping a good rip down the motorway
am tearing my hair out with the ptc heater wiring , i think i may now have to leave it disconnected which i dont want to do
suprising how much u miss the car when its off the road
oh happy days, lolol
